摘　　要：以银基汞膜电极为工作电极，微分电位溶出法测定了对氨基苯磺酸中铅和镉的含量．以玻碳预镀金膜电极为工作电极，微分电位溶出法测定了对氨基苯磺酸中泵和砷的含量．对方法的精密度，准确度进行了实验验证，结果表明本法简单、快速、灵敏、可靠，获得的结果较好．The contents of Pb and Cd in sulphanilic acid was determinated by DPSA with a thin film of mercury on a silver eletrode, and the contents of Hg slid As with a thin film of gold film on a glassy carbon electrode. The precision and accuracy had been studied. The results showed that this method was simple, high speed, sensitive and reliable.
